Choose the Missing a step in the given solution to the inequality : -x- 10 > 14 +2x-x - 10 > 14 +2x
-3x - 10 > 14

Answer 1
Answer:

Answer:

  A:  -3x > 24

Step-by-step explanation:

The missing step above is the result of adding 10 to both sides of the inequality.

____

Comment on the solution of this inequality

The solution shown is correct and gives correct results, but it requires that you divide by a negative number. That division can be by a positive number if the first step is to add x to both sides. Then the second step is to subtract 14 and you get ...

  -24 > 3x

Division by a negative number is not required, and the direction of the inequality stays the same:

  -8 > x

Further comment on the solution

Using left-pointing inequality symbols (< or ≤) arranges the left-right order of the operands the same way they are arranged on the number line. That is, for the solution to this inequality, all of the values of x are to the left of -8 on the number line. Writing the inequality in the form ...

  x < -8

can help you see that. A bit of mental gymnastics is required when the inequality is written ...

  -8 > x

and you want to graph or choose values of x that match this result. Of course, once you have -8>x, you can easily swap sides to make it x<-8.

define the null and alternative null hypothesis for the following. also, explain what it would mean to make a type 1 error and explain what it would mean to make a type 2 error. the newspaper in a certain city had a circulation of 15,000 per day in 2010. you believe that the newspaper circulation is more than 15,000 today

Answers

Answer:

(A)

Null hypothesis: Newspaper circulation in the city per day was = 15,000 in 2010

(B)

Alternative hypothesis: Newspaper circulation in the city today is > 15,000

(C)

Type 1 Error: This is the rejection of a true null hypothesis. It is the acceptance of the alternative hypothesis when the null hypothesis is true.

(D)

Type 2 Error: This is the non-rejection of a false null hypothesis. It is the acceptance of a null hypothesis when it is false.

Step-by-step explanation:

In statistical theory, the complete absence of any of these errors is virtually impossible.

Find the perimeter of WXYZ. Round to the nearest tenth if necessary.

Answers

Answer:

C. 15.6

Step-by-step explanation:

Perimeter of WXYZ = WX + XY + YZ + ZW

Use the distance formula, d = √((x_2 - x_1)^2 + (y_2 - y_1)^2) to calculate the length of each segment.

✔️Distance between W(-1, 1) and X(1, 2):

Let,

W(-1, 1) = (x_1, y_1)

X(1, 2) = (x_2, y_2)

Plug in the values

WX = √((1 - (-1))^2 + (2 - 1)^2)

WX = √((2)^2 + (1)^2)

WX = √(4 + 1)

WX = √(5)

WX = 2.24

✔️Distance between X(1, 2) and Y(2, -4)

Let,

X(1, 2) = (x_1, y_1)

Y(2, -4) = (x_2, y_2)

Plug in the values

XY = √((2 - 1)^2 + (-4 - 2)^2)

XY = √((1)^2 + (-6)^2)

XY = √(1 + 36)

XY = √(37)

XY = 6.08

✔️Distance between Y(2, -4) and Z(-2, -1)

Let,

Y(2, -4) = (x_1, y_1)

Z(-2, -1) = (x_2, y_2)

Plug in the values

YZ = √((-2 - 2)^2 + (-1 -(-4))^2)

YZ = √((-4)^2 + (3)^2)

YZ = √(16 + 9)

YZ = √(25)

YZ = 5

✔️Distance between Z(-2, -1) and W(-1, 1)

Let,

Z(-2, -1) = (x_1, y_1)

W(-1, 1) = (x_2, y_2)

Plug in the values

ZW = √((-1 -(-2))^2 + (1 - (-1))^2)

ZW = √((1)^2 + (2)^2)

ZW = √(1 + 4)

ZW = √(5)

ZW = 2.24

✅Perimeter = 2.24 + 6.08 + 5 + 2.24 = 15.56

≈ 15.6
